When U.S. military trainers handed a new Afghan Police officer, Mohammad Ismail, his AK-47 to defend his remote Afghan village he immediately turned and used it on Americans soldiers. Ismail killed two U.S. service members.
The latest of nine U.S. service personnel gunned down in two weeks by their supposed Afghan allies.
Another similar attack happened several provinces over where two more U.S. service members were wounded.
The United States has spent a total of $20 billion to train and equip the Afghan military force of 340,000 to fend off the Taliban.
In the wake of the recent attacks all U.S. service members have been instructed to carry a loaded weapon with them at all times.
The question is how should the United States deal with the rising friendly fire incidents?
